Perma-Guard Fossil Shell Flour®

Perma-Guard Fossil Shell Flour® is known worldwide for its extremely pure quality Diatomaceous Earth or DE, an eco-friendly naturally organic material from the purest fresh water source. DE is a fossilized deposit of microscopic shells created by one-celled plants called Diatoms. These plants inhabit all the waters of the earth, and serve as the basic food for aquatic life, just as grass is the basic food for land animals. Some of these deposits, shifted to dry land.

Not all deposits of diatomaceous earth or the diatoms present in those deposits are the same.  The shape of the diatom must be tubular with holes on the walls. It is important to have a consistent shape diatom without any unwanted sediment and it must be fresh water because the diatoms form a harder shell and is less fragile than those in salt water.  Salt-water deposits contain a mix of diatom species. These deposit's shapes and sediments are inconsistent, making them unusable for our products. Of the 600 deposits in the US only four are considered "food grade" by FDA standards. Other food grade deposits may contain higher amounts of sediment and clay that make them less effective. After analyzing many other food grade deposits we are satisfied that Perma-Guard Fossil Shell Flour® is the purest form of diatomaceous earth.

Fossil Shell Flour® is a very pure form of diatomaceous earth used as an anti-caking feed

Derived from an extremely pure fresh water deposit of the diatom Melosira Preicelanica

Safe for all mammals.

It is an inert mineral dust of natural origin, contains no synthetic chemicals

Made from freshwater fossilized shells called diatoms, it comes in the form of a chalky powder, much like flour.

Is 89 - 95 % amorphous silica content.

Odor free, tasteless, and has an indefinite shelf life.

Originally granted a patent to be added to animal food.

Fossil Shell Flour® anti-caking agent is to be mixed at a rate no more than of 2% of the dry weight of the rations. For instance, for one hundred pounds of feed, 2 pounds of feed is replaced by 2 pounds of Fossil Shell Flour® .

All regulated products are sold by the information on the label. Fossil Shell Flour® is OMRI listed.

For D.E. to be called "Codex," it must meet the following requirements:

Item	Requirement	Perma-Guard Results
Arsenic (ppm)	not more than 10 ppm	<10
Lead (ppm)	not more than 10 ppm	<10
Non-Siliceous Substance %	not more than 25% on dried basis	11.0%
PH	passes test	7.3
Loss on Drying %	natural powders not more than 10%	6.2
Loss on Ignition	natural powders not more than 7% on the dried basis

 

DO NOT USE POOL GRADE DE!

The filtration  on DE used for pools or other water filtration is a larger mill and is crystalline silica which can cause lung and gut problems or even death. It has been heated and the silica becomes a solid.
